Entamoeba histolytica phospholipase A and lysophospholipase activities from a vesicular subcellular fraction (P30) were analyzed. The products, obtained using specific substrates labeled with 14C or 3H, indicated the presence of phospholipase A1 and A2 as well as lysophospholipase L1 activities. The enzymes detected could participate in phospholipid metabolism and the alkaline phospholipase A2 may contribute to E. histolytica cytopathogenicity.
对溶组织内阿米巴来自囊泡亚细胞部分(P30)的磷脂酶A和溶血磷脂酶活性进行了分析。使用用14C或3H标记的特异性底物获得的产物表明存在磷脂酶A1和A2以及溶血磷脂酶L1活性。检测到的这些酶可能参与磷脂代谢,碱性磷脂酶A2可能有助于溶组织内阿米巴的细胞致病性。
